[0002] At present, the range hood is an essential household appliance in the kitchen. The range hood quickly sucks away the oil fume generated during the cooking process and discharges it outdoors, enabling users to enjoy the cooking pleasure more comfortably. The range hood forms a negative pressure cavity concentrated near the oil net through the fan assembly inside it to absorb the oil fume. The air inlet resistance at different positions of the oil net is different, and the existing oil net holes are generally evenly distributed, which is not conducive to improving the smoking efficiency.

[0003] Therefore, there is an urgent need to provide an oil net and a range hood to solve the above problems. Summary of the Utility Model

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] The oil net includes two first net plates arranged at intervals in the left-right direction. A plurality of first net holes are formed in the first net plate. The first net plate has a first side and a second side opposite to each other in the front-back direction. The opening ratio of the first net plate near the first side is greater than that near the second side.

[0010] As an optional solution, the area of the first net holes near the first side is larger than that of the first net holes near the second side.

[0011] As an alternative, the first wire mesh is divided into a first area and a second area which are arranged adjacent to each other in the front-back direction. The first area is close to the first side, and the second area is close to the second side. The lengths of the plurality of first mesh holes in the second area increase sequentially from front to back and are all smaller than the lengths of the first mesh holes in the first area. The lengths of the plurality of first mesh holes in the first area are equal.

[0012] As an alternative, in the first area, the width of the first mesh hole closest to the first side is greater than the widths of the remaining first mesh holes.

[0013] As an alternative, the two first wire meshes are inclined, and the ends of the two first wire meshes close to each other are higher than the ends far from each other.

[0014] As an alternative, the first mesh hole is a strip-shaped mesh hole, and the plurality of first mesh holes on the same first wire mesh are arranged in parallel;

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] This embodiment provides an oil mesh 100 and a range hood, as Figures 1 to 3 shown. The range hood includes a housing 200, a fan assembly 300, and the above-mentioned oil mesh 100. A negative pressure chamber 201 is provided inside the housing 200, the fan assembly 300 is arranged in the negative pressure chamber 201, an installation opening 202 is provided on the lower side of the negative pressure chamber 201, and the oil mesh 100 is arranged at the installation opening 202. The fan assembly 300 forms a negative pressure in the negative pressure chamber 201 to suck oil fume, so that the range hood has a good oil fume suction capacity. The oil mesh 100 serves as a front-end filtering device of the range hood and is used to realize the separation of oil fume during the process of oil fume entering.

[0039] Specifically, asFigures 1 to 3 As shown in the figure, the housing 200 includes a main chassis 203 and a smoke collecting hood 204 connected to the lower part of the main chassis 203. An air duct 2031 is formed inside the main chassis 203. The air duct 2031 is located in the negative pressure chamber 201. A smoke collecting chamber is formed inside the smoke collecting hood 204. The oil net 100 is integrally arranged in the smoke collecting chamber in a front-high and rear-low inclined manner. The smoke collecting hood 204 can collect and intercept the diffused oil fume, and use the negative pressure area at the installation port 202 to suck the oil fume into the air duct 2031 and the negative pressure chamber 201 of the range hood in sequence, improving the oil fume suction effect of the range hood. Optionally, the oil net 100 is detachably connected to the smoke collecting hood 204, which is convenient for the disassembly and installation of the oil net 100 and facilitates the disassembly and cleaning of the oil net 100.

[0040] Specifically, as Figure 2 and Figure 3 shown, the fan assembly 300 includes a motor 301, a centrifugal impeller 302 and a volute 303. The volute 303 is fixedly arranged in the negative pressure chamber 201. The centrifugal impeller 302 is rotatably arranged in the volute 303. The motor 301 is located inside the centrifugal impeller 302 and one end is fixedly connected to the volute 303. The output end of the motor 301 is connected to the centrifugal impeller 302. The motor 301 drives the centrifugal impeller 302 to rotate, thereby forming a negative pressure in the negative pressure chamber 201 to suck the oil fume. The sucked flue gas is discharged from the air outlet of the volute 303. In this embodiment, as Figure 2 shown, along the axial direction of the motor 301, the motor 301 is installed near the front side of the negative pressure chamber 201. Therefore, the motor 301 divides the negative pressure chamber 201 into a main air inlet side 2011 at the rear side and a secondary air inlet side 2012 at the front side, that is, the motor 301 is arranged near the secondary air inlet side 2012. Due to the obstructive effect of the motor 301 itself, the air inlet resistance of the secondary air inlet side 2012 is large and the wind force is small, so the air intake volume is relatively small. The air inlet resistance of the main air inlet side 2011 is small and the wind force is large, so the air intake volume is relatively large. In another alternative embodiment, the motor 301 can also be installed near the rear side of the negative pressure chamber 201. At this time, the main air inlet side 2011 is located at the front side and the secondary air inlet side 2012 is located at the rear side.

[0041] However, some existing range hoods do not consider the difference in air inlet resistance between the main air inlet side 2011 and the secondary air inlet side 2012. The mesh holes on the oil net 100 are generally evenly distributed, which is not conducive to improving the smoking efficiency.

[0042] To solve the above problems, as Figure 4 and Figure 5As shown in the figure, the oil screen 100 includes two first screen plates 10 arranged at intervals in the left-right direction. A plurality of first screen holes 11 are provided on the first screen plates 10. The first screen plates 10 have a first side 12 and a second side 13 that are opposite to each other in the front-back direction. The first side 12 corresponds to the main air inlet side 2011 of the range hood, and the second side 13 corresponds to the auxiliary air inlet side 2012 of the range hood. The opening ratio of the first screen plate 10 near the first side 12 is greater than the opening ratio near the second side 13. Along the axial direction of the motor 301, the first side 12 is located on the side away from the motor 301 of the second side 13. Exemplarily, in this embodiment, since the motor 301 is located on the front side, the first side 12 is located on the rear side and the second side 13 is located on the front side. In other embodiments, if the motor 301 is located on the rear side, the first side 12 is located on the front side and the second side 13 is located on the rear side.

[0043] For the oil screen provided in this embodiment, a plurality of first screen holes 11 are provided on the two first screen plates 10, and the oil fume is filtered through the first screen holes 11. Among them, in order to meet the air intake requirements at different positions, the opening ratio of the first screen plate 10 near the first side 12 is greater than the opening ratio near the second side 13. Therefore, the opening ratio of the first side 12 is higher, and the oil fume is more likely to pass through the first screen holes 11 on the first side 12, making the flow efficiency of the first side 12 high and the air intake volume large, while the opening ratio of the second side 13 is lower, and the flow efficiency of the oil fume is relatively slow and the air intake volume is relatively small. With such a setting, the air intake volume of the first side 12 can be strengthened, thereby strengthening the air intake volume of the main air inlet side 2011 of the range hood, which helps to improve the smoking efficiency.

[0044] In this embodiment, as Figure 4 and Figure 5 shown, the first screen holes 11 are strip-shaped holes, and the strip-shaped holes extend substantially in the left-right direction. A plurality of strip-shaped holes are arranged at intervals in the front-back direction to cover the entire first screen plate 10. With such a setting, it is possible to maximize the area of the first screen holes 11 as much as possible under the limited area of the first screen plate 10, increase the air intake area, make the air intake more smooth, and improve the air intake efficiency of the range hood. In other alternative embodiments, the first screen holes 11 can also be a plurality of small holes covering the entire first screen plate 10, such as small round holes or small oval holes, etc., as long as it is ensured that the opening ratio of the first screen plate 10 near the first side 12 is greater than the opening ratio near the second side 13.

[0045] Furthermore, as Figure 4 shown, the area of the first screen holes 11 near the first side 12 is greater than the area of the first screen holes 11 near the second side 13 to meet the requirement that the opening ratio of the first side 12 is greater than the opening ratio near the second side 13. Therefore, the area of the first screen holes 11 near the main air inlet side 2011 is larger, and the area of the first screen holes 11 near the auxiliary air inlet side 2012 is correspondingly reduced. With such a setting, it helps to strengthen the air intake volume of the main air inlet side 2011 of the range hood and improve the smoking efficiency.

[0046] Specifically, as Figure 4 shown, the first mesh plate 10 is divided into a first area 14 and a second area 15 (the area enclosed by the dashed line) that are adjacent to each other in the front-rear direction. The first area 14 is close to the first side 12, and the second area 15 is close to the second side 13. The area of the first area 14 is larger than that of the second area 15. The lengths of the multiple first mesh holes 11 in the second area 15 increase sequentially from front to back and are all smaller than the lengths of the first mesh holes 11 in the first area 14. The lengths of the multiple first mesh holes 11 in the first area 14 are equal. It should be noted that the equal lengths here do not mean exactly equal in the strict sense, but approximately equal. With such a setting, the oil mesh 100 focuses more on the air intake volume of the main air inlet side 2011. The mesh area in the first area 14 is larger, and the mesh area in the second area 15 is relatively smaller, which helps to increase the air intake volume of the main air inlet side 2011 of the range hood and is conducive to maximizing the smoking efficiency. Secondly, the increasing setting of the lengths of the multiple first mesh holes 11 in the second area 15 can also ensure the air intake volume of the secondary air inlet side 2012.

[0047] It should be noted that the specific width and quantity of the first mesh holes 11 are not specifically limited here and can be adaptively adjusted according to actual needs.

[0048] In this embodiment, as Figure 4 shown, the first mesh plate 10 is a non-isosceles trapezoid or a non-isosceles triangle, and the shorter waist of the first mesh plate 10 is arranged close to the first side 12, and the longer waist is arranged close to the second side 13. With such a setting, the layout requirements of the multiple first mesh holes 11 in the above-mentioned first area 14 and second area 15 can be met, so as to maximize the opening area on the first mesh plate 10 and at the same time maximize the utilization of the first mesh plate 10.

[0049] In an alternative embodiment, in combination with Figure 4 , in the first area 14, the width of the first mesh hole 11 closest to the first side 12 is greater than the widths of the other first mesh holes 11. That is to say, the width of one first mesh hole 11 located at the rearmost side can be set to be the largest, and thus the area is also the largest. With such a setting, the air intake volume of the main air inlet side 2011 of the range hood is further increased, and the smoking efficiency is maximized.

[0050] In an alternative embodiment, as Figure 5 shown, the two first mesh plates 10 are inclined and symmetrically arranged, and the ends of the two first mesh plates 10 that are close to each other are higher than the ends that are far from each other. Among them, in an alternative embodiment, the ends of the two first mesh plates 10 that are close to each other can be overlapped, so that the two first mesh plates 10 are directly connected together to form a conical oil mesh 100; or, in another alternative embodiment, as Figure 4 and Figure 5As shown, one end of two first mesh plates 10 close to each other is arranged in parallel, and the two are connected by a connecting part 40 to form a trapezoidal oil mesh 100. Among them, the connecting part 40 can be a non-ventilated structure or a ventilated mesh plate structure.

[0051] With such a setting, combined with Figure 1 , when the oil mesh 100 is installed in the installation opening 202, the middle of the oil mesh 100 is concave upward, which can increase the distance between the middle of the oil mesh 100 and the stove below, increase the operation space of the user, and improve the user experience. At the same time, the first oil mesh 100 is inclined, which can increase the area of the overall negative pressure area below the first mesh plate 10 and effectively improve the smoke extraction effect of the range hood.

[0052] In an optional embodiment, multiple first mesh holes 11 on the same first mesh plate 10 are arranged substantially in parallel. With such a setting, the maximum opening area on the first mesh plate 10 can be achieved. The oil and smoke driven by the airflow pass through the first mesh holes 11 more evenly and smoothly, forming a stable and uniform negative pressure area on the lower side of the first mesh plate 10, improving the oil and smoke extraction efficiency, and also achieving the effects of guiding and reducing noise. By reasonably setting the distance between adjacent first mesh holes 11, the opening area can be maximized on the premise of ensuring the structural strength of the first mesh plate 10, and the oil and smoke extraction efficiency can be better improved.

[0053] In an optional embodiment, combined with Figure 4 and Figure 5 , along the directions in which the two first mesh plates 10 face away from each other, the width of the first mesh holes 11 gradually increases. With such a setting, the distance between the higher part of the oil mesh 100 and the fan assembly 300 is relatively close, and the wind pressure is relatively large. Therefore, reducing the width of the first mesh holes 11 can reduce the air volume, and further reduce the pressure of the negative pressure area formed on the lower side of the corresponding oil mesh 100. The distance between the lower part of the oil mesh 100 and the fan assembly 300 is relatively far, and the wind pressure is relatively small. Increasing the width of the first mesh holes 11 can increase the air volume, and further increase the pressure of the negative pressure area formed on the lower side of the corresponding oil mesh 100. By gradually increasing the width of the first mesh holes 11 from high to low, the pressure of the negative pressure area on the lower side of the oil mesh 100 can be balanced, thereby improving the stability of the negative pressure area and better extracting oil and smoke. It should be noted that in this embodiment, the adjacent sides of two adjacent first mesh holes 11 are arranged in parallel.

[0054] Such as Figure 4 and Figure 5As shown in the figure, the oil screen 100 further includes a frame 30 and two second mesh plates 20 arranged at intervals in the front-rear direction. The second mesh plates 20 are respectively connected to the two first mesh plates 10. The frame 30 is connected to the bottom perimeters of the first mesh plates 10 and the second mesh plates 20. A plurality of second mesh holes 21 are provided on each of the second mesh plates 20. The plurality of second mesh holes 21 are arranged at intervals in the left-right direction. The second mesh holes 21 can be selected as strip-shaped mesh holes. The frame 30 facilitates the installation of the oil screen 100 on the smoke collecting hood 204. The second mesh holes 21 on the second mesh plates 20 can further increase the passing amount of oil fume, compensate for the air intake volume, improve the overall ventilation volume of the oil screen 100, and further improve the oil fume suction efficiency of the range hood.

[0055] It can be seen from this that the structure of the first mesh plate 10 provided in this embodiment can be applied to oil screens 100 in various forms such as conical oil screens, trapezoidal oil screens, two-sided air intake oil screens, four-sided air intake oil screens, and five-sided air intake oil screens.

[0056] Optionally, the first mesh plate 10, the second mesh plate 20, and the frame 30 are of an integrally formed structure. In this way, the connection structure between the whole is more stable, and it is more convenient to manufacture, improving the structural stability, reducing the overall cost, and directly installing the integrally formed structure on the range hood can reduce the installation difficulty.

[0057] In an alternative embodiment, as Figure 5 shown, a convex edge 17 surrounding the first mesh hole 11 protrudes from the first mesh plate 10. The convex edges 17 of adjacent two first mesh holes 11 form an oil guiding groove 18. A sump 31 is recessed on the frame 30. The sump 31 is communicated with the oil guiding groove 18. Among them, the convex edge 17 protrudes from the side of the first mesh plate 10 close to the fan assembly 300. In addition, a convex edge 17 surrounding the second mesh hole 21 also protrudes from the second mesh plate 20. The convex edges 17 of adjacent two second mesh holes 21 also form an oil guiding groove 18 communicated with the sump 31. The oil liquid adhering to the upper surfaces of the first mesh plate 10 and the second mesh plate 20 can flow along the oil guiding groove 18 into the sump 31. Through the sump 31, the flowing-down oil stains can be better collected, keeping the overall oil screen 100 clean, preventing the oil stains from dripping, and the sump 31 is integrally formed on the frame 30, without the need to additionally provide a special oil receiving structure, reducing the cost.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
